Hi All,


I am trying to model the steam reforming of ethanol to produce hydrogen, which fluid package should I use on Aspen HYSYS.

Hi there


I was also coincidentally interested in this type of technology since some months ago. I have read a couple of papers regarding the experimental procedures and special catalyst developments, but none of them seems to deal with the mathematical modelling yet.








As far as i have checked, the peng-robinson correlation seems fair for the steam methane reforming, but for accounting for the ethanol-water interaction, i am not sure this correlation is still accurate. Moreover, SRK should not be used for non-ideal chemicals such as alcohols, acids or other components; they are more accurately handled by activity models or PRSV EoS. I would think it would be even better represented by using the PC-SAFT correlation. In any case, the ethanol-water mixture is highly non-ideal and the ethanol reforming process is also achieved at high temperatures. The additional amount of oxygen in the ethanol makes the chemistry a bit more complicated than just reforming oxygen-free methane.
